HIRAM WALTER HOLMES, OF OAKVILLE, CONNECTICUT.

SASH-FASTENER.

To all whom it may concern:

Be it known that I, HIRAM WALTER HOLMES, a citizen of the United States,residing at Oakville, in the county of Litchfield and State ofConnecticut, have invented certain new and useful Improvements inSash-Fasteners, of which the following is a specification, referencebeing had to the accompanying drawings.

This invention relates to certain new and useful improvements in sashlocks and has for its object to provide a device of this character whichwill permit of the adjustment of the sashes for purposes of ventilation,and is adapted to absolutely lock said sashes against movement toprevent the entrance of intruders into the apartments.

Another object is to provide a lock of simple construction which isadapted to be mounted upon the top of the lower sash, adjacent to thewindow frame, said lock having a plurality of slidable bolts adapted toengage in sockets in the upper window sash and in the frame.

A further object resides in the rovision of suitable means for holdingsaic locking bolts in their locked or unlocked positions whereby theiractuation will be effectually prevented by the attempted relativemovement of the sashes.

With these and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure l is a perspective view of aportionof the window sashes and frame, showing my improved lock arrangedin operative position; Fig. 2 is an enlarged top plan view, the top ofthe lock casing being removed; Fig. 3 is a section taken on the line 33of Fig. 2; Fig. 4 is a detail perspective view of the bolt actuatingelement; Fig. 5 is a detail perspective view of one of the slidingbolts; Fig. 6 is a similar view of the holding spring; Fig. 7 is adetail view of the key; and Fig. 8 is a similar view of one of thesocket casings. 7

Referring more particularly to the drawings A and B indicate the lowerand upper sashes, respectively, and C the window frame in which saidsashes are mounted in the usual manner.

Upon the top of the lower sash, preferably Specification of LettersPatent.

Serial No. 539,087.

at the left hand side thereof, my improved lock is mounted. This lockcomprises the casing 5 which is provided with a removable top or coverplate 6 adapted to be seated upon the upper edges of the body of thecasing and secured thereto by means of suitable screws 7 which aredisposed through the cover plate and through the bottom of the casing,said screws entering the sash rail. The lock is further secured to thesash by means of the downwardly extending ears 8 which are struckoutwardly from the bottom of the casing and disposed upon the side ofthe sash rail, said ears receiving suitable fastening screws.

Arranged within the lock casing for sliding movement are the lockingbolts 9 and 10. These bolts are disposed at right angles to each other,and the longer locking bolt 9 is adapted for longitudinal movement andis engaged in the window frame in a manner to be hereinafter set forth.The other of the locking bolts 10 has transverse sliding movement and isadapted to engage with the side of the upper sash to lock the sameagainst movement. It will be observed that the outer end of the lockcasing is semi-circularly formed between the longitudinal edges thereof,as shown at 11. Between this semicircular portion and one side of thecasing the locking bolt 9 is adapted to move. It is further guided inits sliding movement by means of the stud 12 secured in the bottom ofthe lock casing and extending through the cover plate 6 thereof. Similarguiding studs 13 are also formed upon each side of the transverselymovable bolt 10 and have their upper ends disposed through suitableopenings in the cover plate. An opening of suitable diameter is, ofcourse, provided in the side of the lock casing through which the bolt10 moves. Normally the locking bolts are disposed as shown in Fig. 2 otthe drawii'igs, wherein it will be noted that their inner ends are flushwith the side and end of the lock casing when in retracted position.

An actuating element 14 is pivotally mounted for oscillatory movementwithin the casing, and comprises a substantially triangular-shaped body15 through which the pivot pin 16 is disposed. Diverging arms 17 areintegrally formed with this body and the outer ends of said arms areformed with longitudinal slots 18. Each of the bolts is formed with aflattened under face on its inner end, as shown at 9 and 10,respectively, and depending from these flattened faces are the pins 19.These pins are disposed in the slots 18 in the outer ends of thediverging arms 17, said arms moving on said pins in the actuation of thelocking bolt. The point of the triangular body portion 14: is reduced,as shown at l-fl, and is adapted to be engaged by resilient blade 20.One end of this blade is secured upon a stud 21, and adjacent to saidend it is disposed against the side of the lock casing. The majorportion of the spring blade, however, is diagonally extended, as clearlyshown in Fig. 2, and has its free end disposed in one corner of thecasing and engaged with the inner end of the locking bolt 9.Intermediate of its ends the blade 20 is formed with a plurality ofcorrugations 22. The pointed end let of the actuating member is adaptedto be engaged in one of these corrugations and yieldingly held againstunintentional movement by the spring blade 20. WVhen the actuatingmember is moved by the insertion of a suitable key into the lock, thepoint thereof will move over the central corrugation and bend or flexthe blade, and when the bolts have been moved outwardly in the casing totheir locking positions, the point of the actuating member will bedisposed in the other of the corrugations and securely held in suchposition. The inner end of the bolt 9 is preferably beveled, as shown at23, for engagement with the end of the blade 20. The body of theactuating member let is provided adjacent to its outer end with thesocket or recess 24 which is adapted to receive the end 26 of a key 25.This socket is disposed immediately beneath an arcuate slot 27 in thecover plate 6 of the lock casing. An opening 28 is also provided in theplate 6 adjacent to the slot 27 and is adapted to receive the shortprojection 29 formed on the end of the key, the portion of the lockcasing between the slot 27 and opening 28 being received between theprojecting studs 26 and 29 formed on the end of the. key.

In the side rail of the window sash and in the face of the window frame,a plurality of openings or sockets 33 are formed. These sockets areadapted to be protected or reinforced by the tubular sheet metal casings34 which are disposed therein and are each provided with an annularflange on its outer end and the laterally extending ears 35 which areformed with suitable openings to receive the fastening screws 36. In theoperation of the device the locking bolts are adapted to be received inthese tubular casings, which will prevent wear upon the sash and frameand overcome the vibration of the window sashes which would result froma loose engagement of the locking bolts in the sockets.

In the operation of my improved sash lock,

after the sashes have been properly adjusted in the frame to secure thedesired amount of ventilation at the top and bottom of the window, thekey 25 is inserted into the lock, the longer stud thereof ext-endingthrough the arcuate slot 27 and into the socket or recesses 24 in theactuating member 14: while the shorter stud 29 is disposed in theopening 28 in the cover plate. They key is then turned, and theactuating member oscillated upon its pivot against the tension of theholding spring blade 20. Upon this movement the arms 17 will be moveddownward and outward in the lock casing, and slide the bolts thereinoutwardly into engagement in the sockets in the side rail of the upperwindow sash and the window frame. Owing to the slot and pin connectionbetween these arms and the bolts, the arms will slide upon the pinsduring the oscillatory movement of the actuating member, while thelocking bolts are moved in a constant direction. The locking bolts areheld in their locking positions by means of the holding spring 20 in themanner previously set forth, and the retraction of said bolts iseffectually prevented until the key' is again inserted into the lock tomove the oscillatory actuating member.

From the foregoing it is believed that the operation and many advantagesof my improved sash lockwill be readily apparent without necessitating amore extended description. But few parts are employed in theconstruction of the lock and they are thoroughly incased and protectedwhereby the proper operation of the device is insured. The locking boltsare simultaneously moved at right angles to each other, and the lockingengagement of the bolts with the window frame and sash is very quicklyattained by but a slight movement of the key, thus facilitating the easyand rapid looking or unlocking of the window sashes.

WVhile I have shown and described the preferable form of the variousparts and the manner in which they are to be associated, it will beobvious that the same is susceptible of numerous modifications withoutmaterially departing from the essential features or sacrificing any ofthe advantages of the invention.

Having thus described the invention what is claimed is:

A lock of the character described comprising a lock casing having acover, sliding bolts mounted in said casing having angular relativemovement, an oscillatory actuating element pivotally mounted in saidcasing comprising a body and diverging arms integrally formed therewith,said arms having movable connection with the inner ends of said lockingbolts, the body of said. actuating element having a key receiving sockettherein, a corrugated spring blade arranged within the casing engagedwith said element and adapted to yieldingly hold the bolts againstactuation, said cover plate having an arcuate slot above the socket insaid actuating member and an opening adjacent to said slot, a key havinglugs formed upon one end adapted to be received in said slot andopening, one of said lugs being disposed in the socket in the actuatingmember and adapted to move the same to slide the 10 bolts when the keyis turned.

In testimony whereof I hereunto afiix my signature in the presence oftwo Witnesses.
